Description

Roller convenient to maintain

Technical Field

The utility model relates to a roller convenient to maintain is applicable to all kinds of roller equipment in metallurgical field.

Background

With the trend development of the metallurgical industry towards large scale, high specification and high speed, the maintenance problem of the metallurgical equipment is more and more emphasized. Metallurgical mechanical equipment generally has the characteristics of complex structure, large volume, high precision requirement and the like, and continuously works under the conditions of high temperature, heavy load, dustiness and corrosion, so that some equipment needs to be frequently replaced and repaired, such as a roller, a coating roller and the like.

For roller bodies which need to be frequently ground, the roller end supporting seat also needs to be frequently installed and disassembled. On one hand, the grinding machine can grind the roll surface only after tightly pushing the central hole of the roll end, so the roll end supporting seat is convenient to disassemble; on the other hand, before the repaired and polished roller body is produced again, the roller end supporting seat needs to be convenient to install at two ends of the roller body.

The roll end support typically includes a bearing 101, a bearing outer end cap 102 and a bearing inner end cap 103, the bearing outer end cap 102 being removably attached to the bearing inner end cap 103 and restraining the bearing 101 to the roll body. During normal production, the roll end bearing blocks are all axially fixed, and the roll end bearing blocks are not axially restrained externally in the roll changing process. In the conventional design, a bearing 101 is axially positioned by an end baffle 104 inside a roller end bearing seat, so that the roller end bearing 101 seat is axially fixed (see fig. 1); before the roller body is polished, the shaft end baffle 104 is required to be removed to remove the roller end supporting seat completely, and after the roller body is polished, the roller body is reversely mounted, so that time and labor are wasted. The improved design is that a shaft end baffle 104 (see figure 2) is directly removed, the roller end supporting seat is more convenient to disassemble and assemble before and after the roller body is polished, but the roller end supporting seat often slips out of the roller end in the actual roller changing and hoisting process.
